Figure 8-17. Shared Bus Interface

The shared bus interface is probably the simplest and least expensive interface. How- ever, the performance of the Inte1386 DX microprocessor may drop tremendously because the Intel386 DX microprocessor must wait for the 82586 to complete its bus operation before it can access the bus. This wait can be several hundred eLK cycles.
